That is scaled so that the mean vertex area across the brain has a value of 1.

Peace,

Matt.

I just checked, that S900 group average package includes the following:

S900.All.midthickness_MSMAll_va.32k_fs_LR.dscalar.nii
S900.midthickness_MSMAll_va.32k_fs_LR.dscalar.nii
S900.midthickness_MSMAll_va_ratio.32k_fs_LR.dscalar.nii

The first contains the midthickness vertex areas for all subjects.  The 2nd is 
the average across those subjects.

Matt: What does the *va_ratio* file represent?

These days we use the group average surfaces and correct for group averaging 
shrinkage with the appropriate vertex areas.  Hopefully those files were 
included in the release:

${StudyFolder}/${Group}/MNINonLinear/fsaverage_LR32k/${Group}.midthickness${RegName}_va.32k_fs_LR.dscalar.nii,
 which you can split out into GIFTI shape files with wb_command -cifti-separate 
for use in commands that want a GIFTI file.

Peace,

Matt.

Thank Tim and Jennifer very much for your answers!

I have one more question about the spatial operation commands of Connectome 
Workbench. If I use the commands “-cifti-gradient” or “-cifti-smoothing” for 
processing HCP group-averaged maps, should I use the atlas midthickness 
surfaces (“Conte69.L.midthickness.32k_fs_LR.surf.gii” and 
“Conte69.R.midthickness.32k_fs_LR.surf.gii”) or HCP S900 group-averaged 
surfaces (“S900.L.midthickness_MSMAll.32k_fs_LR.surf.gii” and 
“S900.R.midthickness_MSMAll.32k_fs_LR.surf.gii”) for the input arguments of 
these commands?

Thank you!

HI Aaron,


In answer to your #2 question... There are S900 group average data and surfaces 
available in the
900 Subjects Group Average Data
section of the HCP S900 project page in ConnectomeDB

https://db.humanconnectome.org/data/projects/HCP_900



Best,
Jenn

Subject: [HCP-Users] Some questions about the usage of Connectome Workbench

Dear HCP experts,

I have some questions about the usage of Connectome Workbench for displaying 
custom group-level ICA maps stored in a *.dtseries.nii file.

1.    I am currently able to save the figure (similar to the format of the 
figure displayed in Scene 3 of Connectome Workbench v1.0 Tutorial) of each 
component map of a group ICA *.dtseries.nii file by clicking on “File>Capture 
Image” manually and then change to the next component map and do the same again 
manually, but this way is petty time-consuming if I have a lot of ICA 
components (frames) in a *.dtseries.nii file. How could I batch export these 
surface view figures via Connectome Workbench by using some commands?

2.    I found R440 group-averaged surface files in the WB 1.0 Tutorial Dataset. 
However, are there any S900 group-averaged surface files available for use in 
the HCP dataset?

3.    How could I get the anatomical region name (in terms of Brodmann or any 
other brain atlases) of each grayordinate above a user-defined threshold in a 
custom map using Connectome Workbench (similar to the function of clicking 
“Report” button of xjView)?

Thank you very much!
